wherein: Manifestly, three pieces of material, which must Figure 1 is an end elevation of a receptacle be properly cut so as to exactly fit in place, must constructed in accordance with the invention, be employed. Also, machinery must be provided 68 Figure 2 is a front elevation of the same, for forming the individual parts and additional employed.

costly machinery is necessary to assemble the parts. This not only involves high manufacturing costs but also increases cost of material due to the number of parts necessary. Further, the finished receptacle has three seams and the tendency of the seams to open or become corroded, resulting in leakage, is great. It is. further pointed out that a receptacle formed in such a manner has angular edges or corners which not only detract from its appearance but also increase the possibility of accidental tipping or turning over of said receptacle, causing spilling of the fluid contained therein. Also these corners found in the usual receptacle provide a place for accumulation of gum or other deposits of extraneous material from the fluid in the receptacle which aid corrosion and deterioration of the receptacle. In addition, particles of such deposits frequently flake off and enter the eduction tube to stop up the fluid passage therethrough.

It is noted that this improved receptacle is formed of only two sections, each of which oomprises a single piece of material formed as hereinbefore described, and joined along a single seam. It will be seen, therefore, that due to thereduced number of sections required in this receptacle, the number of operations necessary in its formation, as well as the cost of materials and manufacture is materially reduced. The provision of the single seam substantially eliminates leakage due to splitting, corroding or breaking open of seams, because, obviously, the possibility is reduced to one third as compared to the usual receptacle, which has three seams. Further, by

1 forming the receptacle with rounded ends, a symmetrical body is produced, thereby enhancing the appearance of the same. Also, all. angular edges and corners are eliminated, and. the rounded ends act to maintain the receptacle always in. an upright position because, if the receptacle should accidentally be placed on end, said rounded ends will naturally and immediately return said. receptacle to an upright position. Therefore, unintentional spilling of the fluid from the receptacle is substantially eliminated. Obviously, the generally ellipsodial shape of this receptacle provides a continuous inner surface, and thereby eliminates corners or angular surfaces, whereby normal formation of deposits of extraneous ma-- ,terials from the fluid within the receptacle is eliminated.

Another form of the invention is shown. in

- those already described. In" this form, however,

the edges of both sections are bent outwardly-to form laterally directed external flanges which engage-each other when the sections are placed together. The flanges are then crimped, or beaded, as at M, to securely fasten them together, whereby the sections are fastened toeach other to form the hollow receptacle.

I The receptacle may be mountedon the usual sprayer barrel in any suitable manner and any suitable means for filling the receptacle may be. In Figures 4 to 7, the receptacle is. provided with an-opening l6 which extends transa versely thereof, and which is formed in the top of the upper section II. The forward endof a sprayer barrel I5. is positioned within the opening and is soldered or otherwise secured therein. The opening is of such size as to receive only the lower portion of the barrel, whereby the major portion of said barrel is above the receptacle. The barrel is provided with an opening I! in its lower portion which is disposed within the receptacle, and the usual fluid eduction tube I8 extends downwardly therethrough into the receptacle. A removable sprayer head 19 is screw threaded on the forward end of the barrel, and it will be seen that this head may be removed and the receptacle filled through the end of the barrel, fluid entering the receptacle through the opening I! in said barrel.

In Figures 6 and 7 the receptacle is mounted on the barrel in the same manner as hereinbefore described. However, this type of sprayer has an integral head closing the forward end of the barrel. For filling the receptacle, a filler neck 20 is secured in an opening 2| in the upper section II, and a closure cap. 22 is screw threaded on the end of said neck. It will be seen that the receptacle may be filled through this opening and that the cap prevents spilling of the liquid therefrom.

The receptacle is shown mounted on the sprayer barrel in another manner in Figures 8 and 9. In this form a central opening 23 is provided in the top of the upper section II and an upwardly extending collar 24 is soldered or otherwise secured therein and has screw threads formed thereon. The sprayer barrel is provided with a cap 25 secured to its underside, which cap is adapted to be screwed onto the collar 24 of the receptacle, whereby said receptacle and barrel are connected together. It will be seen that to fill the receptacle with the fluid to be sprayed, it is only necessary to unscrew the cap by rotating the barrel, and thus the barrel and receptacle are separated and the opening uncovered.

It is noted that the means. by which the receptacle is mounted on the barrel and the means by which the receptacle may be filled are. not to be limited to the-forms shown, as it is conceivable that many variations thereof may be employed without departing from the spirit of the invention.

What I claimand desire to secure by Letters- Patent, is:

A sprayer comprising a container and an elongate cylindrical pump barrel with a sprayer head at one end and securedadjacent said endto the container, said container comprising an elongate body consisting of two sections united by a seam in a plane extending throughits lon gltudlnal axis to form an ellipsoidal. receptacle substantially cylindrical for a distance between substantially hemispherical ends, said elongate container body having an opening in its upper portion and means for connecting the pumpbarrel therewith so that its sprayer head will extend forwardly beyond the container, said pump barrel having an-opening through its lower surface. providing communication between pump barrel and container and through which any fluid which. may be in the barrel willall drain back into the container, and conduit means ex tending through said opening in the pump. barrel into thecontainer for conducting container fluid to the sprayer head.
